"[Plin. Nat. 23.66.] - PLUMS: FOUR OBSERVATIONS UPON THEM.
The leaves of the plum, boiled in wine, are useful for the tonsillary glands, the gums, and the uvula, the mouth being rinsed with the decoction every now and then. As for the fruit itself, it is relaxing to the bowels; but it is not very wholesome to the stomach, though its bad effects are little more than momentary.”
